Bearing Capacity of Strip Footing on Reinforced Foundation Beds with Inclined Reinforcement

Usually reinforcement is arranged (placed) horizontal underneath the footings, to restrain developed tensile strains in soil, which in turn increase the reinforced sand bed shearing resistance by means of interfacial bond resistance and limited by tensile strength of its own. Present work analyses geotextile reinforced foundation bed with reinforcement placed inclined downward from edge of footing towards free end at an inclination varying from 0 to 10° and evaluated the normalized bearing capacity values. Sand bed reinforced with inclined reinforcement overlying clay is studied by computing enhancement in normalized bearing capacity against reinforced foundation bed with reinforcement placed horizontally. The variation of normalized bearing capacity with angle of shearing resistance of sand bed, length of reinforcement, sand bed density are studied. Sand bed reinforced with inclined reinforcement quantify the increase in bearing capacity when compared with conventional method of placing reinforcement horizontally.
